ERASER-HOLDING DEVICE AND THE LIKE.

Application led May 23,

My intention relates to improvements in eraser holding devices and thelike and has for its primary object the two-told purpose of vprovidingan eraser holding device for mechanical pencils which will securely gripand tightly hold an eraser in any desired position, and secondly, due toits construction and resiliency,will prevent the loss of a cap adaptedto cover said eraser holder and eraser, when the frictional engagementbetween said cap and said eraser holder has been materially weakened dueto constant removal of said cap from said eraser holding device for thepurpose of using the eraser.

Another object oi my invention is to pro vide an eraser holding devicewhich is simple of construct-ion and economical to manufacture.

Other objects will appear as this description progresses, referencebeing had to the accompanying drawings, in which Y Fig. 1 is a sideelevation of the wellknown Eversnarp pencil, with the inner mechanism,to which is attached the cap, partly unscrewed from the barrel.

Fig. 2 is a longitudinal sectional view of the cap and eraser holdingdevice embodying my invention, and disclosing the attachment oit saideraser holding device to the lead magazines.

Fig. 3 is a longitudinal sectional view of said eraser holder on line3-3 ot Fig. 2, and

Fig. a is a cross sectional view on line 4-t of Fig. 3.

Referring to the drawings, 10 indicates a pencil barrel tapered as at 11to form theV aperture 12 through which a. writing lead is propelled orrepelled by means within said barrel 10. Inasmuch as the mechanism ofthe pencil forms no part of my invention it is not deemed necessary toburden this application with a detailed description ot same.

As is most clearly discernible in 3,

the eraser holding device 14 has its upper edge thereof slightly turnedin to 'form the flange 15; said flange is adapted to bite into and holdan eraser inserted in said eraser holding device.

4^ lip 16 is so formed that the free end of the lip is slightly bentdownwardly, causing said end to protrude or extend inwardly toresiliently grip the eraser. Due to the bendi921. serial rra-471,549.

ing of the lip 16 downwardly, thefree end with the free end or the lip16, tightly grips and holds an eraser in any desired position. thus whenan eraser has been worn down to the level ot the ridge 15, it can bepulled outwardly any desired distance, care being taken however, to seethat the lower end of the eraser is not pulled out beyond the point ofcontact with the free end of the lip, thus preventing the lip frombiting into the eraser. Because of this arrangement, very little of theeraser will be wasted, which is a common fault .of most eraser holdingdevices attached to pencils or the like now on the market.

It will be noted from the drawings that I have illustrated but one lip.However, more lips can Ybe formed in the eraser holder if deemeddesirable I have found upon eX- periment that two lips, smaller indiameter than the one illustrated in the drawings,and formed oppositeeach other, will cause a greater amount of ifrictional engagementbetween said cap and said eraser holding device.

There-fore, while I have illustrated and described the preferred form otconstruction for carrying my invention into effect, the structure iscapable of variation and modification without departing from the spiritof the invention.

Having described my invention, what I claim as new `and desire to secureby Letters Patent is 1. An eraser holder having means tor gripping aneraser, and a cap adapted to enclose the end ot said holder, the saidmeans being further adapted to releasably lock said cap againstlongitudinal movement relative to said holder.

2. An eraser holder having resilient means tor gripping an eraser, and acap adapted to enclose the end of said holder, the said means beingfurther adapted to releasahly look said cap against longitudinalmovement relative to said holder.

3i An eraser holder having' movable means `for gripping an eraser, and'af cap adapted to enclose 'the end of said holder, the said means beingfurther adapted to releusalolyv lock said cap against longitudinalmovement relative to said holder.

4. An eraser holder having means for retainingv a portion of an eraserwithin the holder and a resilient tongue adapted to Contact With theeraser, and a Cap for covering the eraser7 the sai(L tongue beingadapted to releasahly lock .said Capagainst longl tuclinal movement.

In witness whereof I have hereunto subscribed my name.

J E JOHNSON.
